Ingredients
- 1 pound chicken thighs, boneless and skinless
Chicken thighs offer more moisture and flavor compared to breasts, making them ideal for casseroles. - 1 cup sundried tomatoes, packed in oil
These bring a tangy and slightly sweet taste that elevates the flavor profile of the casserole. - 1 cup heavy cream
Heavy cream creates that luscious, creamy texture that makes the dish indulgent and satisfying. - 1 cup mozzarella cheese, shredded
Mozzarella melts beautifully, adding a gooey, stretchy texture that complements the dish perfectly. - 1 cup prosciutto, chopped
Adding prosciutto gives a salty crunch that contrasts delightfully with the creamy elements. - 2 cups pasta (penne or fusilli)
Choose short pasta shapes that capture the creamy sauce and ingredients in every bite. - 2 tablespoons olive oil
Olive oil is essential for sautéing and adds a richness that blends well with the other ingredients. - 2 cloves garlic, minced
Garlic infuses the dish with an aromatic depth that complements the sundried tomatoes beautifully. - 1 teaspoon salt
Salt enhances flavors, bringing out the best in every ingredient. - 1/2 teaspoon black pepper
Black pepper adds a hint of heat and balances the creamy elements. - 1/2 teaspoon red pepper flakes (optional)
For those who enjoy a kick, red pepper flakes elevate the flavor with a gentle spice. - Fresh basil for garnish
Basil adds a burst of fresh flavor, brightening up the dish just before serving.
Directions & Preparation
Step 1: Preheat the oven to 375°F (190°C).
Preheating ensures that your casserole bakes evenly and achieves that golden, bubbly top that we all love. The anticipation of the warm oven gives you just enough time to prep while filling your kitchen with warmth.
Step 2: Cook pasta according to package instructions until al dente.
Al dente pasta adds the right texture, allowing it to hold its shape when mixed with the creamy ingredients. Drain and set aside, but don’t rinse — you want that starchy goodness to help the sauce cling.
Step 3: In a large skillet, heat olive oil over medium heat. Add minced garlic and cook until fragrant, about 30 seconds.
Sautéing garlic in olive oil activates its natural oils and brings out a rich aroma that fills the air. Watch for the transition from raw to fragrant; it happens quickly — you want that perfect golden subtlety without burning.
Step 4: Add the chopped chicken thighs to the skillet, seasoning with salt and black pepper. Sauté until browned, about 5-7 minutes.
Browning the chicken not only locks in moisture but also adds a depth of flavor that makes each bite more satisfying. The sound of sizzling chicken is a beautiful music to your ears as the kitchen begins to smell irresistibly delicious.
Step 5: Stir in the sundried tomatoes and red pepper flakes (if using), cooking for an additional 2 minutes.
This step melds the sweet-tart punch of sundried tomatoes into the chicken, enhancing the casserole's flavor base. The colors start to mingle, painting a vibrant dish that’s as eye-catching as it is tasty.
Step 6: Reduce heat and stir in the heavy cream, mixing thoroughly until the sauce is creamy and well combined.
As the cream swirls with the other ingredients, a luxurious sauce will begin to form. The aroma intensifies, inviting everyone to the table as the mixture thickens slightly, promising a rich texture in the final dish.
Step 7: In a large bowl, combine the cooked pasta and cream sauce mixture until evenly coated.
Gently folding the pasta into the sauce ensures every piece is enveloped in the creamy goodness. The harmony of flavors coats each strand, letting you experience the depth of flavor with each forkful.
Step 8: Transfer the pasta and chicken mixture to a greased 9×13 inch casserole dish.
Opting for a larger casserole dish helps the flavors meld beautifully during baking. Spreading it evenly allows that crispy, cheesy layer to top the pasta perfectly, ensuring there's enough for everyone at the table.
Step 9: Top the mixture with shredded mozzarella and chopped prosciutto.
The mozzarella will melt into gooey patches, while the prosciutto crisps up, creating that savory crunch. Seeing the cheese slowly melt under the heat is almost as satisfying as the flavor it contributes to the dish.
Step 10: Bake in the preheated oven for 25-30 minutes, or until the cheese is bubbly and golden.
The final baking transforms the casserole into a bubbling masterpiece. Keep a watchful eye as it cooks — the rich aroma will make it hard to wait, but you’ll know it's ready when that delightful golden crust develops on top.
Step 11: Remove from the oven and let sit for 5-10 minutes before serving. Garnish with fresh basil.
Allowing the casserole to rest ensures that the layers set perfectly, making it easier to serve. The final touch of fresh basil adds a burst of color and a refreshing herbaceous note that wakes up the entire dish.

The Magic of Sundried Tomato Pesto
Sundried tomato pesto serves as the heart of this casserole, bringing a unique depth of flavor that transforms the ordinary into the extraordinary. Its concentrated sweetness and fragrance harmonize brilliantly with the rich cream and savory chicken, making every bite a delightful surprise.
Crispy Prosciutto: The Secret Crunch
Adding crispy prosciutto at the end is a game-changer. Its salty, crisp texture not only contrasts with the creamy interior but also adds an irresistible crunch that keeps you reaching for another bite. This balance elevates the dish from a standard casserole to an experience.
Perfect Cheese Pairings
While mozzarella melts beautifully, consider blending it with parmesan for added depth. Parmesan introduces a nutty flavor that enhances the overall profile, resulting in a wonderfully layered taste sensation with every forkful.
FAQs
What can I use if I can't find sundried tomatoes?
You can substitute sundried tomatoes with roasted red peppers or even sun-dried tomato paste for a similar flavor profile.
Can I make this dish spicier?
Add more red pepper flakes or a dash of hot sauce to the cream sauce for a flavorful kick.
What if my sauce turns out too thick?
If the sauce is too thick, simply stir in a splash of chicken broth or extra cream until you reach your desired consistency.
Can I prepare this dish in advance?
Absolutely! Prepare everything up to the baking step, cover it, and refrigerate overnight, then bake when you're ready to serve.
What should I do if my chicken looks undercooked?
Make sure to slice the chicken into smaller pieces; they will cook through in the oven when the casserole is baking.
How can I scale this recipe for a larger crowd?
Simply double the ingredients and use a larger casserole dish. Make sure to increase baking time slightly.
Can I use dried herbs instead of fresh basil?
You can use dried basil, but reduce the amount as dried herbs are more concentrated. Fresh basil adds brightness that dried cannot fully replicate.
